Application tiled May 2l, 18H6. Serial No. 202,8S1. (No model.)

struction and combination of devices, that will be more fully set forthhereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my invention,with thenear wheel removed.

Fig. 2 is partly an elevation and partly a vertical sectional view ofthe same. Fig. 3 is a top plan view, partly in section. Fig. 4 is a rearelevation. Fig. 5 is a detail perspective view of one of the bearingsfor the drivingshaft. Fig. 6 is a vertical section of one of thebearings for the rear axle. Fig. 7 is an elevation of a modified form ofmy invention, with the near wheel removed. Fig. -8 shows an auxiliaryseat attached to backbone.

A represents a frame, which is composed of parallel side arms, B,connected at their front ends by a curved arm, C, and provided with aforwardly-projecting shank or arm, D. The arms B are connected togetherby transverse bars E and F, which are arranged respectively near therear and front ends of the frame. rlhe central portion of the frame isbent downwardly from a horizontal line, as shown in Fig. l. The rearends of the arms B are provided with laterally-projecting bearing-boxesG, in which are arranged a series of anti-friction rollers, g, theprojecting spindles at the ends of thesaid rollers being journaled inrings g', which are placed in the ends of. the bearing-boxes.

H represents a transverse shaft, which is journaled in the bearings G,and extends outwardly beyond the outer sides of the frame A. To one endof the said shaft is rigidly attached a large wheel, I, and to the otherend of the said shaft is loosely attached a similar wheel.

K represents a sprocket-wheel, which is loose on the shaft H, and islocated near one of the arms B, and L represents a smaller osprocket-wheel, which is also loose on the shaft, and is located nearthe opposite arm B. A slidingclntch, M, is placed on the shaft H, and isadapted to move back and forth thereon, so as to engage with either ofthe wheels K and L, or to be moved to the central portion of the shaftbetween the said wheels and out of engagement with either of them.

To the lower ends of the bars B are attached bearing-blocks N, which areprovided with depending plates a, having longitudinal horizontal slotsa. Bolts at pass transversely through the said slots and through thesides of the bars B, and thereby permit the boxes N to be movedforwardly or rearward] yin the frame A, and to be adjusted thereon atany desired point within the limit of the slot u.

O represents thedriving-shaft, whichis j ouri naledy in the boxes N, thesaid boxes being provided with anti-friction rollers similar to therollers g of the bearings G.. To `the center of the shaft O is attacheda friction-wheel, P, and to the ends of the said shaft are attachedcrank-arms O. The said arms are provided near their outer ends withslots O2, and extend in opposite directions from the shaft O. Pedals Oare attached to the outer ends of the crank-arms by means of transversebolts, which extend through the-slots O2 and are secured therein at anydesired adjustment by means of clamping-nuts, which are screwed onto theinner ends of the said bolts. On one side of the friction-wheel P, andin a line with the small sprocket-wheel L, is a large sprocket-wheel,It, which is rigidly attached to the shaft O, and on the opposite sideof the friction-wheel, and in aline with the large sprocket-wheel K, isa small sprocketwheel, S, which is also rigidly attached to the shaft O.

T represents a brake, which is fulcrumed on the cross-bar F and isprovided with a rear- Ward-extending curved arm, T', having its innerside covered with rubber or leather or other suitable material andadapted to bear against the periphery of the friction-wheel. An arm, T,projects forwardly from the brake and is provided at its outer end witha suitable pedal.

U represents the backbone of the tricycle, which is provided at itslower rear end with the vertical forks U', which are attached to IOO therear ends of the bars B. From one of the said bars depends a step, V. Inthe front ends of the frame A and of the backbone U is journaled aguiding-rod` XV, which is provided at its lower end with the forks XV',be-

tween which is journaled the small steeringwheel X, which runs in frontof the large wheels I. The upper end of the guiding-rod is reduced,thereby forming a shoulder, w, and upon the said upper end of the rod isplaced acoiled extensile spring, w', the lower end of which bears uponthe shoulder w and the upper end of which bears under the front end ofthe backbone. To the upper end of the guiding-rod XV is attached theusual steering-arms, Y.

Z represents the seat, which is supported upon a curved flat spring, Z',the said spring bearing upon the backbone, and is provided with a clip,Z2, having a set-screw, which elnbraces the backbone and permits theseat to be adjusted forwardly or rearwardly thereupon to suit theconvenience of the rider.

a represents a lever-arm, which is fulcrumed to the backbone between theforks thereof, and extends downwardly and engages the feathered slidingclutch on the shaft H.- The upper end of the lever a works in atransverse loop or keeper, b, which is secured to the backbone and isprovided on its rear side with a series of openings, b. The lever-armhas a stud, b2, which projects from its rear side and is adapted toengage either of the series of openings b and thus lock the said armthereto. It will be readily understood from this description that whenthe upper end of the leverarm a is moved to the right the sliding clutchwill be moved to the left on the shaft H, so as to lock the largesprocket-wheel K to the said shaft, and that by moving the upper end ofthe leverarm to the left the sliding clutch will be moved to the-right,thereby disengaging the large wheel K .and locking the small wheel L tothe shaft H. XVhen the lever-arm a is in a vertical position, thesliding clutch is arranged between t-he wheels K and L and out ofengagement with both 'of them, and therefore the said wheels are bothloose on the shaft H. An endless sprocket-chain, d, connects the smallwheel L with the large wheel B, and a similar endless chain, e, connectsthe large wheelK and the small wheel S. By thus providing thedrivingshaft with the large and small wheels, which are connected,respectively,to the small and large wheels of the main shaft of thetricycle, and by providing means for throwing either of the wheels outof gear with the main shaft of the tricycle, it will be readilyunderstood that the machine may be caused to run either very rapidly ornot so fast, as may be desired, by moving the lever a., and withoutaltering the speed of the driving-shaft O. The tricycle may be thuspropelled very rapidly on level ground and caused to run slowly up anincline, and thus avoid excessive fatigue on the part of the rider.

By providing the guiding-rod XV with the spring w, to support the frontend of the backbone, an easy and pleasant motion is imparted to thetricycle, and the latter is thus prevented from jarring and jolting therider.

f represents a lamp-holder, which is composed of abent arm, f', that isattached to the guiding-rod XV by means of a set screw, h, and bearsupon the front end of the pivotal part of the frame A, thus preventingthe latter from rising on the driving-rod.

k represents an arm,which engages the guiding-rod W, and the front endof said arm is provided with a series of openingsJc. Through one ofthese openings passes abolt, kiwhieh connects the said arm with the bentarm f of the lamp-holder. By means of this construction it will beunderstood that the front arln of the lamp-holder may be adjustedforwardly or rearwardly with relation to the guiding-rod XV, so as tothrow the light from the lamp either to the ground directly in front ofthe machine, or at a considerable distance ahead.

Z represents a seat or platform, which is attached to the rear lowerside of the backbone U by means of a clip, l', and the said seat orplatform is provided with depending supporting-arms Z2,whieh areattached to the forks U of the backbone. The said seat or platformenables the machine to carry two persons.

In Fig. 7 I illustrate a modified form of my invention, in which theframe A is provided with a rearward extension, m,which carries adriving-shaft, o, having a gear-wheel, p, connected to one of the wheelson the shaft H by means of an endless belt, and the shaft ois alsoprovided'at its ends with oppositely-extending crank-arms provided withthe pivoted pedals. From the rear end of the extension m rises avertical standard, s, which carries a vertical]y--adjustable seat, t,supported upon a spring, t. When the tricycle is provided with thisapparatus, it is adapted to be used ,i

double, and each person riding the tricycle can assist in 4propellingit.

Having thus described in my invention, I clai1nl. The combination, in atricycle, of the frame A, the backbone attached thereto, thesteering-rod W, carrying the front wheel, and pivoted to the front endsof the frame A and the backbone, and the spring 'w' on the upper end ofthesteering-rod and bearing under the front end of the backbone, for thepurpose set forth, substantially as described.
